Ga-67 uptake by the male breast under digitalis influence

This report emphasizes that Ga-67 uptake by the male breast can be seen if the breast is exposed to a hormonal milieu of increased estrogen compared with testosterone concentrations. Gynecomastia is a rare side effect of digitalis ingestion and is attributed to its estrogen-like action. We describe a case demonstrating focal Ga-67 uptake in both breasts in a 64- year-old anemic man being treated with digitalis.
